a
Absolute concordance rate = the percentage of those whose self-report of the presence of the index condition agreed with the chart documentation.
b
Sensitivity = the percentage of those with the chart documented index condition who self-reported the condition.
c
Positive predictive value = the percentage of those self-reporting the index condition that had it according to the chart documentation.
